There is very little foxing. What there is is brown spotting occasionally but not commonly, from foreign substance in pages or in margins of old. Only stains are margin ones last couple of pps V. I and first 6 leaves of V. II. No names or writing etc. within.
Paper quality is good but signatures vary a bit- for instance N-OYE V.II paper is browned and not as white as other pages. There are other instances of lesser differences in aging. End papers are loose and edge trimmed by handling(?). Last pages of v. II are wrinkled. Vol. II begins with text- no frontis, preface etc. preface in vol I is XXV pages.
Binding is chipped with pieces of leather torn off and missing to varying degrees but never to where it encompasses even a third of the cover.

The spine labels are present though the lower label (there are two on each vol) on V II is rubbed nearly off.. The spines are good with chipping on the ends. and have raised bands
